Definition
AC power is not present or is too low for proper system operation
The battery voltage is below the 24 V nominal level by 10% or more.
The battery is either below 20 V or completely undetected.
The EPS is drawing more current than it should. Check for faults on the circuit.
The battery charger is either defective or being heavily loaded by batteries. Read charger current at front
panel, if charger current is approximately 3 A, batteries are likely loading the charger. Remove battery
connection and measure the output of the EPS. If the output is 27.6 (or close, temperature dependent),
there is a possibility of depleted batteries or a bad set of batteries. Allow batteries to charge or replace
them if they do not take a charge.
Appears if one or more extra devices (i.e., devices that have not been configured for the IDNAC channel)
are one the system. Only one message appears, regardless of the number of extra devices found.
Comes up during the Earth Fault Search diagnostic function. Once the search is initiated, the front panel
display indicates how far along the search process has progressed (10%, 25%...75%), and then shows
the results of the search. The result either identifies the offending circuit or indicates that the earth fault
could not be found. EPS circuits (IDNet, IDNAC, and aux power) are searched. System alarm and trouble
processing is suspended during the search.
